    en.wikipedia.org/wiki/Diethylsuccinoylsuccinate

    Diethylsuccinoylsuccinate is an organic compound with the formula [CH 2 C(OH)=C(CO 2 Et)] 2 (Et = ethyl). A tetrasubstituted derivative of 1,4-cyclohexadiene, the compound is the enol tautomer of the corresponding cyclohexadione. [1] It is produced by base-induced condensation of diethyl succinate: [2] 2 EtO 2 CCH 2 CH 2 CO 2 Et [CH 2 C(OH)=C ...

  3. Dealkalization of water - Wikipedia

    en.wikipedia.org/wiki/Dealkalization_of_water

    The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.

  4. Mitsunobu reaction - Wikipedia

    en.wikipedia.org/wiki/Mitsunobu_reaction

    The reaction mechanism of the Mitsunobu reaction is fairly complex. The identity of intermediates and the roles they play has been the subject of debate. Initially, the triphenyl phosphine (2) makes a nucleophilic attack upon diethyl azodicarboxylate (1) producing a betaine intermediate 3, which deprotonates the carboxylic acid (4) to form the ion pair 5.

  5. Advanced oxidation process - Wikipedia

    en.wikipedia.org/wiki/Advanced_oxidation_process

    Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). [1]

  6. Diethyl succinate - Wikipedia

    en.wikipedia.org/wiki/Diethyl_succinate

    Diethyl succinate is the diethyl ester of succinate. It is a colorless liquid with the formula (CH 2 CO 2 Et) 2 (Et = ethyl). The organic molecule contains two ester groups. This ester is a versatile chemical intermediate. A colorless liquid, diethyl succinate is formed by Fischer esterification of succinic acid and ethanol.

  7. Dissolved air flotation - Wikipedia

    en.wikipedia.org/wiki/Dissolved_air_flotation

    Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms ...
